I have a question before I do anything.I have the previous compiz running on my debian testing. All is working except for ccsm not launching.Do I remove everything (purge all the packages) and then install all the debs from the repository?Thanks

Here's another repo I set up with rebuilds from the tuxfamily compiz-reloaded repo. They conflict with the ones in my other repo, so hopefully apt or aptitude will replace them successfully. Most of the packages have "-reloaded" tacked onto the name. Just the compiz-reloaded package brings in all the rest, but it can't hurt to remove the other packages first.

The new ccsm-reloaded's main difference is that it's using a python-gtk3 GUI instead of python-gtk2, but I don't know if that will get rid of the error...I have some doubts.

This is usually a problem when you install a package with a Python installation that was compiled with the fpectl module (--with-fpectl compilation flag), and then switch to a Python installation that was compiled without this flag.

Further search results seem to indicate that fpectl was indeen removed in Debian a few months ago. There a a lot of bug reports about problems caused by that. My python installation doesn't have fpectl.

Steve, You mentioned in a different post that you had got compiz updated for Buster. My system has some compiz installed but the ccsm is not working. What would be the best way to update my system to get all the packages working? I'll do some beta testing if you would like me to.ThanksDan
